maybe it scales in a non-linear fashion
why can someone blow up the moon and planets at a power level of 5 figures and below, but power levels over a million can only make Dodger Stadium sized craters
ah, but your power level rises when performing a super attack. so it was probably more like 560 people, a number i can readily believe.
No, cause 1400 was the absolute maximum that Piccolo had while performing a super attack.
